70002442 Selectin a single object in webLibrary

Summary

When I click with the mouse , I want to select one object at a time. For example there is a selected object, I want to leave it and select the one I clicked last.

Solution

It can be done by overwiting vdcanvas.vdSelectionModified event as follow

//filter the selection for move copy rotate etc commands
 vdcanvas.vdSelectionModified = selectionmodified;

        function selectionmodified(eventargs) {

            //clear hilighted of previous selected entities
            for (var i = 0; i < eventargs.action.customData.length; i++) {
                eventargs.action.customData[i].selected = false;
            }
            vdcanvas.ActionDrawEntities(eventargs.action.customData, true);

            //select the first entity item in the selected collection
            eventargs.selectedItem.selected = true;
            eventargs.action.customData = [eventargs.selectedItem];

            //cancel no other item selected only the first one
            eventargs.cancel = true;

        }
